Background
With the improvement of modern living standard, the application of the ice block is more and more extensive. Some refrigerators have an ice maker provided in a freezing chamber thereof to make ice cubes by using the cold energy of the refrigerator. Before making ice blocks, water needs to be injected into the ice maker from the water storage tank in advance by using the water supply assembly. However, the temperature in the ice maker is often relatively low due to ice making. Therefore, if the water filling port of the water supply assembly leaks water, on one hand, the water in the ice maker is excessively filled, and the ice blocks are bonded together; on the other hand, water in the water filling opening is very easy to be iced by the influence of cold air in the ice maker, so that a pipeline is blocked, and the ice maker cannot make ice.
In order to solve the problem of water leakage at the water injection port, the prior art provides various solutions. One of the problems is that water in a water supply pipeline is pumped back into a water storage tank by a water pump in a water supply assembly after water injection is finished, but the problem of insufficient back pumping of the water pump often exists, so that the water leakage phenomenon still exists at a water injection port, and the energy consumption is increased due to the fact that the water pump works uninterruptedly; and secondly, a water valve mechanism is additionally arranged in the water supply assembly, the problem of water leakage of the water filling port due to the siphoning effect of water is solved by utilizing the throttling characteristic of the water valve mechanism, and if the joint of the water supply pipeline and the water valve mechanism is not installed in place or is not tight due to aging and abrasion, the external air enters the water supply pipeline, so that the problem of water leakage of the water filling port is still caused.
Therefore, in order to solve the above problems, it is necessary to design a new type of ice making device and a control method thereof.

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the scope of the present invention.
According to fig. 1, the present invention provides an ice making apparatus 100, comprising an ice making machine 110 and a water supply assembly for injecting water into the ice making machine 110, wherein the water supply assembly comprises a water storage tank 1, a water pump 2 and a water supply pipeline 3; the water supply assembly further comprises a control valve 4 arranged on the water supply pipeline 3, the water supply pipeline 3 comprises a water inlet pipe 31 and a water outlet pipe 32 which are respectively arranged at two sides of the control valve 4, and the control valve 4 is provided with a first connector 41 connected with the water inlet pipe 31, a second connector 42 connected with the water outlet pipe 32 and a third connector 43 communicated with external air; the control valve 4 has a first state and a second state; when the control valve 4 is in the first state, the third port 43 is closed, and the water inlet pipe 31 is communicated with the water outlet pipe 32; when the control valve 4 is in the second state, the first port 41 is closed, and the water outlet pipe 32 is communicated with the outside air through the third port 43. Therefore, in the process of filling water into the ice maker 110, the control valve 4 is in the first state, that is, the water inlet pipe 31 is communicated with the water outlet pipe 32, and water is continuously filled into the ice maker 110 from the water storage tank 1 through the pumping action of the water pump 2; after the water injection is completed, the water pump 2 stops working, the control valve 4 is switched to the second state, the water outlet pipe 32 is an open pipeline communicated with the outside, the water remained in the water outlet pipe 32 in the water injection process flows out once under the action of gravity, and then the water outlet pipe 32 is close to one end of the ice maker 110, so that the problem of water leakage cannot occur.
Specifically, in this embodiment, the third port 43 is connected to a vent pipe 33. Moreover, the end of the vent pipe 33 departing from the third port 43 extends to above the water storage tank 1 and is spaced from the liquid level in the water storage tank 1. When the water injection is completed and the control valve 4 is in the second state, a part of the water originally remaining in the water supply pipeline 3 during the water injection is discharged from the air pipe 33 to the water storage tank 1 by gravity.
In particular, in the present embodiment, the water storage tank 1 includes a bottom wall 11 and a side wall 12 extending upward from the bottom wall 11, and the bottom wall 11 and the side wall 12 enclose to form an accommodating space 13; the end of the vent pipe 33 facing away from the third joint 43 is located above the inside of the accommodating space 13, so that water discharged from the vent pipe 33 is prevented from splashing outside the water storage tank 1 to the greatest extent. Preferably, a waterproof fence (not shown) is formed around the upper edge of the side wall 12 to further prevent water splash from splashing outside the water storage tank 1 due to the instant that the water in the air pipe 33 falls to the liquid surface. Of course, the water storage tank 1 may be provided with other structures for preventing water from splashing, for example, a top cover (not shown) opposite to the bottom wall 11 is additionally provided, and an opening (not shown) for inserting the air pipe 33 and the water inlet pipe 31 and a vent hole (not shown) for communicating the inside and the outside are provided on the top cover, so long as the effect of preventing water falling from the air pipe 33 from splashing outside the water storage tank 1 can be achieved.
As shown in fig. 1, the water inlet pipe 31 extends from top to bottom to a position below the liquid level of the water storage tank 1. In this embodiment, the end of the inlet pipe 31 facing away from the first port 41 extends to adjacent to the bottom wall 11. When the ice maker 110 is filled with water, the liquid level in the water storage tank 1 will be lowered continuously due to the reduction of liquid, and the arrangement can avoid the phenomenon that the water pump 2 is empty due to the fact that water is in the water storage tank 1 but the water cannot be sucked by the water inlet pipe 31 to the greatest extent.
Further, the water outlet pipe 32 has a water injection section 321, and when the control valve 4 is in the second state, the water retained in the water injection section 321 can flow under the gravity to be injected into the ice making machine 110. Furthermore, the water outlet pipe 32 further includes a connection section 322 extending from the second interface 42 to an end of the water injection section 321 away from the ice maker 110. In order to reduce the accumulated water in the water supply pipeline 3 for a long time as much as possible, the connection point of the connection section 322 and the water injection section 321 is the highest point of the water outlet pipe 32.
In addition, in this embodiment, the water pump 2 is disposed on the water outlet pipe 32. Of course, the water pump 2 can also be disposed on the water inlet pipe 31, as long as the purpose of the present invention can be achieved that the water in the water storage tank 1 can be continuously injected into the ice maker 110 under the suction action of the water pump 2 when the control valve 4 is in the first state.
In addition, the present invention also provides a control method of controlling the ice-making device 100 as described above, including the steps of:
closing the third port 43 of the control valve 4 and opening the first port 41 of the control valve 4;
controlling the water pump 2 to start, and starting to inject water into the ice maker 110;
the water pump 2 is turned off;
the first port 41 of the control valve 4 is closed and the third port 43 of the control valve 4 is opened.
The water injection amount L of the ice maker 110 is determined according to the water capacity L1 of the ice maker 110 and the capacity L2 of the water injection section 321, wherein L is L1-L2. Also, in the present invention, the method of controlling the water injection amount of the ice maker 110 may be, but is not limited to, the following manner:
(1) accumulating the starting time of the water pump 2, monitoring the working time of the water pump 2 when the water injection amount of the ice maker 110 reaches L, and recording as T; and after the water pump 2 works for a T time period, the water pump 2 is turned off.
(2) Detecting flow, and determining a set flow when the water injection amount of the ice maker 110 reaches L according to the detection position, wherein the minimum value of the set flow is L, and the maximum value is the sum of the capacity of the water inlet pipe 31, the capacity of the water outlet pipe 32 and L; when the flow rate reaches the set flow rate, the water pump 2 is turned off.
(3) Detecting the water injection amount of the ice maker 110 in real time; when it is detected that the amount of water injected on the ice maker 110 reaches L, the water pump 2 is turned off.
Specifically, when the ice maker 110 needs to be filled with water, the third port 43 of the control valve 4 is closed and the first port 41 of the control valve 4 is opened, the water pump 2 is started, and water flows from the water storage tank 1 to the ice maker 110 under the action of the water pump 2; when the water injection amount of the ice maker 110 reaches L, the water pump 2 is turned off and the third port 43 is opened, the first port 41 is closed, at this time, the water outlet pipe 32 is communicated with the outside air through the vent pipe 33, and the water with the water amount of L2 remaining in the water injection section 321 flows to the ice maker 110 at one time due to the gravity, so that the water amount in the ice maker 110 reaches the required water volume L1, and ice making is started. Since all the water in the water injection section 321 flows out, in the process of making ice, the water leakage phenomenon will not occur at the end of the water injection section 321 close to the ice maker 110.
In summary, according to the present invention, by the arrangement of the third interface 43 on the control valve 4, after the water injection of the ice maker 110 is finished, the water outlet pipe 32 is communicated with the outside air, so that the water originally stored in the water outlet pipe 32 flows out from the water injection section 321 or the air pipe 33 at one time under the action of gravity, thereby effectively preventing the water leakage phenomenon from occurring at one end of the water outlet pipe 32 close to the ice making device 100 during the ice making process, and further avoiding the problems of the blockage of the water supply pipeline 3 and the excessive water injection of the ice making device 100; in addition, the invention has simple structure and low manufacturing cost.
It should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art will be able to make the description as a whole, and the embodiments may be appropriately combined to form other embodiments as will be appreciated by those skilled in the art.
The above detailed description is merely illustrative of possible embodiments of the present invention and is not intended to limit the scope of the invention, which is intended to include all equivalent embodiments or modifications within the scope of the present invention without departing from the technical spirit of the present invention.
